Oregon's original e-bike statute dated to 1997 — long pre-dating Class 1/2/3 — and treated all e-bikes as a single category capped at 1,000 W and 20 mph. The state was a 1,000 W outlier from the start (most states use the federal 750 W standard), and HB 4103 kept that 1,000 W cap when overlaying the three-class framework.
The bill's political trigger was the death of Trenton Burger in Bend on 17 June 2023 — one month shy of his 16th birthday. The 15-year-old was riding an e-bike on a sidewalk along Highway 20 when a van turned right into him; he was struck and killed. Trenton's mother became an outspoken advocate for tighter e-bike rules, and Rep. Emerson Levy (D-Bend) introduced HB 4103 in the 2024 short session under the working title "Trenton's Law".

The bill was substantially amended during committee. The introduced version proposed banning all under-16 from Class 2 and Class 3; the enacted version kept that age boundary for Class 2 and 3 but retained Class 1 access for under-16 riders without a license. HB 4103 also created the new parental-liability offence (Class E traffic violation, max $100) targeting parents who let children under 16 operate Class 2 or 3 on a highway. The bill passed the Oregon House unanimously on 28 February 2024, cleared the Senate by a similar margin, was signed by Governor Tina Kotek as 2024 Or. Laws Ch. 12, and took effect 1 January 2025.
